Manufacturing process of raw grain expanded leisure food

Abstract

The invention discloses a manufacturing process of raw grain expanded leisure food, which comprises the following steps: peeling, degerming and expanding corns with high starch content; agitating and flavoring expanded semi-finished products; and drying at moderate temperature. Auxiliary materials used during the agitating and flavoring process comprise the following components by weight percent: 21 to 30 percent of malt syrup, 3.7 to 10 percent of edible oil, 3 to 5.5 percent of white granulated sugar, less than or equal to 0.5 percent of edible salt and 1 to 30 percent of whole milk powder, wherein characteristic flavor agents are moderate, the drying temperature is 85 to 95 DEG C, and the drying time is 25 to 30 min. The outer appearance of the product accords with the consumption psychology of consumers in seeking for natural food; the product breaks the high glucose and high fat mode of the expanded food, does not add any leavening agents, coloring matters and other additives that are adverse to health; and the drying at the moderate temperature at the later state adopts the control of microwave manner and time to avoid the defects that the taste is not crisp due to higher moisture caused by the reason that the traditional raw grain expanded leisure food is only expanded or fried, and can not be dried, the shelf life is shorter, the sanitation index is not up to standard, and adverse factors are caused by frying.

Description

Technical field: [0001] The invention relates to a puffed snack food, in particular to a production process of raw grain puffed snack food which directly puffs and reprocesses raw materials. Background technique: [0002] At present, leisure food is a convenience food favored by consumers. The leisure convenience food made from raw grains can be roughly divided into four categories. The first category is the puffed food that is made of coarsely crushed raw grain and compounded with other raw materials, and then puffed or cooked; this type of product cannot guarantee the characteristic shape of the raw grain, and to a certain extent destroys some of the original raw grain. In the production process, some additives will be added to ensure the taste and properties of the product, and the post-production will cause high sugar or high fat content; the second type is compounded, crushed and briquetting after raw grain is puffed and other production methods, this type of food cann...

Problems solved by technology

The first category is the puffed food that is made of coarsely crushed raw grain and compounded with other raw materials, and then puffed or cooked; this type of product cannot guarantee the characteristic shape of the raw grain, and to a certain extent destroys some of the original raw grain. In the production process, some additives will be added to ensure the taste and properties of the product, and the post-production will cause high sugar or high fat content; the second type is compounded, crushed and briquetting after raw grain is puffed and other production methods, this type of food cannot guarantee the characteristic shape of the raw grain, and either it cannot be eaten directly, or it is easy to cause microbial and other additive pollution in the post-production process; the third category is to add sugar and Flavoring briquettes stick together. Although this type of product maintains the visibility of the characteristic shape of the raw grain, it requires a higher sugar content, or high fat content occurs due to frying in the later stage, the moisture content is too high, the taste is not crisp enough, and the shelf life Shorter and less hygienic indicators; Chinese patent CN1071312 discloses the "processing technology of wheat kernel series food" which is a kind of this type of food. This technology will remove impurities by winnowing wheat, screening, washing, evenly moistening, peeling, Dried into raw wheat kernels; the surface of the raw wheat kernels is sprayed with moisture and puffed into the puffing machine to make puffed wheat kernels.
